After a video was posted to Facebook showing bull sharks in a Queensland canal estate, many locals seemed unsurprised by the risk lurking beneath the water.

Sunshine Coast councillor Jason O'Pray uploaded the video of a pack of bull sharks swimming in a shallow section of the Twin Waters Canal - a canal estate and coastal suburb situated on the northern mouth of the Maroochy River, 95km north of Brisbane.

The video has been viewed more than 300,000 times since being uploaded to Facebook on Thursday.

But of the less than 60 comments the video had received at the time of publication, several weren't shocked with the suburban shark sighting.

"Been catching big bullies in there for years," Kenny Lynch wrote.

"Best left alone. But people just need to stop feeding them to attract them in groups like this. We have been catching them in there for over 20 years before any houses or the grid was even thought about. No point catching and releasing or removing the grid. You will never remove them out of there," Ty Johnston added.

Bull sharks are known for their aggressive nature and are known for their tolerance to less salty waters, commonly being found in rivers and canals.

Sunshine Coast University marine scientist David Schoeman has advised people to stay away - due to the aggressive nature of bull sharks.

"A shark that might be inquisitive doesn't have hands so they'll give it a nudge and if you get on the sharp end of that nudge you'll end up with a hole in you," Professor Schoeman told the Sunshine Coast Daily.
